CASH-CHECKING MACHINE.

Specification of Letters Patent.

Patented April 9, 1907.

Application filed June 20. 1904. Serial No. 213,334.

To all whom it may concerm I Be it known that I, EDGAR GUEss, a subject of the King of Great Britain, and a resident of 31 Tasman road, Clapham, in the 1 county of Surrey, England, haveinvented a certain new and useful Improvement in and connected with Cash-Checking Machines, (for which I have applied for Letters Patent in Great Britain, No. 14,062, dated June24, 1903,) of which the following is a specification.

The present invention relates to improvements in and connected with electrical cashchecking machines, the objects being the prevention of fraud and'recording the total amount of cash registered as having been received.

The invention comprises, essentially, a switchboard with a series of levers or knobs each one of which represents a different value equivalent to one or more cash units, a series of registering-dials in electrical connection with the switchboard, so that they register each individual transaction, and in connectionwith each other, so that they show the total amount, and a cash-receiving till consisting of three separate tills-for gold, silver, and copper, respectivelyeach inclosing a revoluble wheel with four divisions and so arranged as to expose to sight the last coin or coins inserted therein. As the connection between the switchboard and the registeringdials is an electrical one, it willbe seen that the registering-dials can be located in any place distant from the switchboard, so as to be under the direct observation of the manager or other person in authority. a By making use of a suitable system adapted to a particular trade or business in which the apparatus herein described forms an integral feature it is possible not only to prevent or minimize fraud on the part of the employees receiving cash, but to instantly which in many businesses necessitating the tell at any moment the exact total amount received, which in many businesses is of the utmost importance.

In existing cash-checking machines or registers of any commercial value the whole of the mechanism for indicating and recording the cash receipts has been self-contained,

use of a great number of said registers renders them practically of little value, whereas by the present invention any number of separate switchboards located at various places throughout the building can be caused to register the cash receipts at one place.

In the accompanying drawings, which illustrate, byway of example, one method of carrying this invention into effect, Figure 1, Sheet No. 1, is a view in front elevation of the switchboard. Fig. 2, Sheet No. 2, is a view in back elevation thereof. Figs. 3 and 4, Sheet No. 3, are views in side elevation thereof.- Fig. 5, Sheet No. 4, is an enlarged view in section, showing the construction of the switchboard mechanism. Figs. 6,7, and 8, Sheet No. 5, are enlarged broken detail views, in back elevation, plan, and end elevation, respectively, showing the locking mechanism for each knob or slide. Fig. 9, Sheet No. 6, is a view in front elevation of therecording-dials. Fig. 10, .Sheet No. 6, is a viewin back elevation thereof. Figs. 11 and 12, Sheet No. 7, are views, on an enlarged scale, in front elevation of the mechanism for operating the hand of one of the registering-dials, showing two different positions which the parts assume. Figs. 13 and 14 Sheet No. 7, are views, also on an enlarged scale, in plan and end elevation, respectively, of the dial mechanism. Fig. 15,

Sheet No. 8, is a diagrammatic view showing the various electrical circuits and connections. Fig. 16, Sheet No. 9, is a view in front elevation of one of my improved tills. Fig. 17, Sheet No. 9, is a view in plan thereof. Fig. 18, Sheet No. 9, is a 'view' in end elevation thereof, partly in section; and Figs. 19 and 20 are detail views of the till mechanism.

Throughout the views similar parts are marked with like letters of reference.

The switchboard consists of a plate a, carried by a suitable casing a, and having on its front side a series of knobs b, b, 11 and 6 each one of which represents a different value and is so marked equivalent to one or more cash units. The series'bf knobs I), representing farthings, and 1), representing pence, are of one color, and the other series of knobs b representing shillings, and b ,'representing pounds, are of other different colors, so as to render them. easily distinguishable. Each of these knobs is free to slide in a slot of in the plate a and is carried by a plate 0, sliding in guiding-pieces c fixed on the back of the said late a.

vided with cam-shaped plates 0 (see particularly Fig. 7,) ada ted to contact with and move, when the obs are slid in the slots a9, levers (1, cl, (Z and (1 arranged centrally behind the said plates 0 The lever d, ada ted to be moved by the lates 0 carried y the farthing series of nobs b, is pivoted to the casing at d and carries at its free enda contact-piece e, ada ted to make contact with a serles of meta lic teeth f carried by an insulated segmental block f attached to the plate a or casing a. The other levers (1, (Z and d are pivoted at d, d, and d res ectively, to the casing and are ada ted to e moved by the plates 0', carried y the pence series of knobs b, the shillings series of knobs b and the pounds series of knobs 6 respectively. The levers d, (1 and d carry contact-pieces e, e", and 0 respectively, adapted to travel over different series of metallic teeth f ,f and f carried by insulated segmental blocks f f, and

E d ch of the contact-pieces e, 6', 6 and e consists of a metallic plece e pivoted at e and controlled by a spring e. The face of the piece (2 is formed with an insulating material e, so that electrical contact between the piece 6 and the teeth fis not made on the first movement of the lever, but onl on its return movement. The teeth in eac series will correspond in number with the number of units represented b the highest number of the respective series of knobs. The shape of the plates 0 or their distance in relation to the pivoting-points of their respective levers will determine the amount of travel which the said levers will receive on sliding the knobs either to the right or left hand, and so determine the number of teeth with which the contacts will engage.

The levers d, d, (1 and d are held in contact with the plates 0 and controlled by the s rings 9, g, 9 and g, respectively, and the uration of their return movements, after operation by their respective cam-plates, is controlled by dash' ots h, h, W, and 7?, respectively. It wil thus be seen that the speed or duration of the make-and-break in an electrical circuit between any one of the movable contacts 0 and its contact-teeth f is controllable and irrespective of the speed at which the knobs may-be slid in then slots.

The levers d, d, (1 and d besides carrying the hinged contact-pieces, are also each provided with contact-cheeks e adapted to rub and make contact with other pieces f carried, respectively, by the insulated blocks f f f and f when the levers are operated. These contact-cheeks e on contacting with the pieces f 8 complete an electrical circuit in which an electric bell i/or other alarm signal is included, so as to give an audible warning when any one of the series of knobs is operated. A visible warning is also given at the same moment by placing the said contacts 42 and f 8 carried by the levers d and d in circuit with an incandescent electric lamp and the contacts of the other levers d an d in circuit with other lamps y" and j respectively as the be 1 i, are prefera ly carried on the top of the casing a, as shown. Each of the lamps isof a diflerent color. The lam 7', adapted to be lit on operatin any one o the copper series of knobs, may e white, corresponding to the colorof that series of knobs, and the lamps y" and 1', adapted to be lit on operating, respectively, any one of the silver or gold series of knobs, maybe red or yellow, respectively, corresponding to the color of the respective series of knobs.

In order to prevent any knob of a series being operated until the respective lever has completed its return travel from a previous operation, the following lockin device is arranged in connection with eac of the cam-' sha ed operatinglates c. A tri er-sha ed pied; 7c is pivoted at below the gdge of the plate 0 and is so shaped or weighted as to cause its upper end to engage either one of the ends of the said plate 0 The lower-end of the said piece is is adapted to be engaged by the lever when the latter is in a osition of rest, and so keep the upper end of said piece from engagement with the plate 0 It will thus be seen that on operating any one of the plates 0 of a series immediately the lever of that series moves out of contact with the lower ends of the trigger-shaped pieces their upper ends will engage the ends of the remaining plates of that series and prevent them from being operated until the lever has completed its travel.

In order to insure that each of the plates 0 performs the whole of its travel after being These lamps y, y, and j as well once started or to prevent the knobs from being partly slid forward in their slots and then returned without first terminating the whole of the sliding movement in the one direction, the following lockin arrangement is employed: Each of the .ates c carries on its up er side a rack Z, with which a pivoted paw I, carried b the plate a centrally with res ect to said p ates 0 is adapted to engage uring the sliding movement of the said plate, thus preventing any reverse motion of the knob and plate until the rack has passed sufficiently far in the one direction as to be clear of the awl.

The switchboar above described is intended to be laced where it can be conveniently operate by the employees and is in electrical communication (details of the circuits will be presently described) with the recording or registering dials, which may be placed at any convenient'distant part under the direct observation of the manageror proprietor.

"The recording or registering dials and mech -anisinf."(see Figs. 9-14) comprise a suitable ber of divisions found most convenient for the particular business or coinage for which the apparatus is intended to be used. In the present-case the dial n is divided into sixteen equal divisions for registering farthings,

the dial '11 into twelve equal divisions for reg"- istering pence, the dial a into twenty e ual divisions for registering shillings, the dia a into fifty. equal divisions for registering pounds, and the dial n into fifty equal disuitable form of locking mechanism p actuat' visions for. registering multiples of fifty pounds.

Hands or pointers'o, 0, 0 0 and o are caused to travel around their respective dials in the direction of the arrows and so record the amount. Buttons or knobs pon the axles of the hands are provided for setting them at zero, and in order to prevent un. authorized setting of the hands a lockingframe 1) is provided. This frame is provided with collets or bosses p fitting over the knobs p, and is hinged at p to the wall or casing and locked in position so that the collets or bosses inclose the knobs p by fiily e mechanisms of each hand or pointer may e of. any suitable form of electrical step-by-ste movement in electrical connection with t e respective contact-teeth of the switchboard, and the mechanism for carrying forward the maximum amount of one dial to the next one of higher value may be of any well-known type, either mechanical or electrical.

A convenient method of actuating the hands and carrying forward .the totals is illustrated particularly in Figs, 11-14 in which the mechanism t for operating the shilling-dial 113 is shown. On the axle q, carrying on its front side the hand or pointer o and mounted in suitable bearings, isfixed a ratchet-wheel 1', provided with twenty teeth. A rod or bar s is formed in one with or fixed to the core 8' of a solenoid s or electros magnet, which is capable of imparting movement to said bar. Pivoted to this bar s at 1" is a weighted or spring-controlled pawl r adapted to engage the teeth of said ratchetwheel 1' and impart motion to said wheel when the circuit of the solenoid s is completed, causing it to suck or draw in the core 8', and thus move the'rod or bar 8 by making a tail 1- on said pawl r engage, and thereby be tripped by a fixed stop or guide 1". Motion in the reverse or return direction is caused b a suitably-arranged spring 1", engaging .t e said rod or bar 8. A checksprin 1", enga ing the teeth of the ratchet- Whee is provi ed to prevent a reverse rotation of the said wheel.

In order to make one complete revolution of the hand 0 actuate the pointer 0 through one division on the pounds-dial M, the axle q is provided with a single tooth or projection g, which is arranged to completethe circuit of the solenoid actuating the mechanism of the pound-hand 0 This may conveniently be accomplished by causing the tooth q to enga e the one end of a pivoted lever g provi ed with contacts g g, dipping into pots q q, containing merc and which are included in the circuit of the solenoid actuating the mechanism of the hand 0 The contact qis preferably always in contact with the mercury in the pot g, while the other contact g is arrangedto only contact with the mercury in the ot (1 when the lever is depressed by the toot g against a spring or, preferably, an adjustable weight g on the free end of said lever.

. The actuating mechanisms t, t, t and t for the hands a, n, a and n, respectively,

are similar to the one t described above with the exception that the number of teeth of the respective ratchet-Wheels correspond with the numbers of divisions of the respective dials. The carrying-forward mechanisms of the dials n, n, and n are similar to that described with reference to the dial a with the exception that the axle of the hand 0 of thefarthing-dial n carries four teeth q owi to the said dial registering sixteen farthings, or four ence.

Thev various e ectrical circuits and con.-

nections (see Fig. 15) are as follows: The

movable contacts 0, e 6 and e and sliding contacts a are all in electrical connection with one another and by wires 1 in connection with the poles of two batteries'z and z. The teeth f, f, f, and or contacts for the farthing series of kno s b, pence-knobs b, shilling-knobs b3, and pound-knobs 6 re-- spectively,'are connected to the one terminal of the solenoids of the actuating mechanisms t, t, t, and t respectively, by wires 2,

3, 4, and 5. The other terminals of the so- 1 lenoids of the said mechanisms t, t t and t are connected by wires 6 to the other pole of the battery 2 and to the one pole of another battery 2 The contacts f with which the pieces 6 contact on operating any one of the cop er series of knobs b b, the silver series of kno s 6 and the gold series of knobs 12 are connected, respectlvely, with the one terminal of the lamps y, j, and 7' by Wires 7 8 9. The

other terminals of the lamps are connected by wires 10 with the other pole of the battery Z, in which return-circuit is included the bell '11. The hell '1', is of the single-stroke type, working without interruption of the. circuit. The mercury-contact pots g of the actuating mechanisms t, t, t, and t are connected, respectively, to the solenoids of the mechanisms t, t t and t by wires 11, 12, 15, and 13, and in the case of the solenoids of the mechanisms t, 22*, and t to those terminals with'which the wires 3, 4, and 5 are connected, the free terminal of the solenoid of the mechanisms t bein connected to the return-circuit wire 6. lhe other mercurycontact ots g are connected with the other pole of t e battery 2 by wires 14. The various wires of the switchboard are connected to the terminals as a; on the to of the casing a and are preferably incloserf by a removable casing a. The terminals 3 y of the various wires of the recordin -dials are contained within a separate compartment m formed on the back upper art of the casing m and to which access may e obtained without removing the back board covering in the actuating mechanisms of said dials.

The machine operates as follows: On the supposition that a cash payment of one and one-half pence has been made the first knobof the series I) is slid from the left to the right hand, or vice versa, should the knob happen to be on the right-hand side. This motion when half completed will cause the lever d, owing to the cam-sha ed plate 0 engaging therewith, to assume t he position indicated in dot-and-dash line in Fig. 5. This movement of the lever having brought the contacts e and f 8 into engagement, the lamp 3' will glow and the bell sound, calling attention to the fact that themachine has been operated. On this first movement of the lever the contact-piece e will pass above the teeth f without making contact therewith, owing to the insulated piece 6 engaging said teeth, but on its return movement the piece e contacts with the last tooth making contact therewith, then passing out of contact again breaks the circuit before contacting with the next tooth, and so on, thus producing six, in the present instance, distinct makes and breaks in the circuit before the lever comes again to rest. Each of these interruptions causes the solenoid of the actuating mechanism t to operate, thus rotating the ratchet-wheel and driving 'itforward six teeth, one tooth at a time. The hand 0 of the dial n will then indicate 2 on the second uarter of the dial, equivalent to six fart ings, and the hand 0 of the dial n will be at 1 thereon, because after the fourth tooth-of the ratchet-wheel was engaged the tooth g on the spindle thereof came into engagement and depressed the mercury contact-lever, thereby causing the solenoid of the actuating mechanism t to rotate the hand 0 throu h one of the divisions on the dial/n. It 1 thus be seen that the hands will then register 2 on the farthings-dial and -1 on the pence-dial, equivalent to one and one-half pence, corresponding to the amount denoted on the knob operated. The lamp 1' ,will continue to glow, owing to the contacts 6 and f 8 remaimng in engagement, until the dials have recorded the amount, so giving notice that any knob of the series con trolling said lamp is free to be again operated.

The cash-receiving till, which is illustrated in Figs. 16 to 19 of the accompanying draws ings, consists, essentially, of a vertically-arranged casing it, having a drawer u arranged at its lower end and carrying at its upper part a semicircular casing u. The casing a is adapted to be secured to the edge of the counter or other convenient place in such a manner that only the casing 1& projects above the surface of said counter. The sides a of the semicircular casing 11, are formed of any suitable transparent material, preferably' glass. The casing a is arranged so as to be readily detached from the casing u in order to allow of the transparent sides a being cleaned inside and also to allow of their being replaced in case of breakage. A convenient arrangement is to form the said casing a with spring-arms u, adapted to slide down the inner sides of the casing u and to be retained in position by engaging studs a fixed to the sides of the casing a. In order to release the arms u" from engagement with the studs u access is obtained to the interior of the casing by means of the drawer a, which is provided with any suitable locking device. A revoluble wheel having four divisions is adapted to be rotated within the casing a and partly within the casing a. This wheel preferably takes the form of four e uallyspaced radial members to, each of whic is of a like length and of atriangular shape in cross-section, having an axle w mounted to revolve in bearings formed in the casing a. On the axle w is fixed a ratchet-wheel-W,

having four teeth corresponding to the members w and with which engages a spring-controlled pawl w, carried b a bevel-pinion w loosely mounted on sai axle. The bevelpinion w is adapted to gear with a similar pinion L05, carried by a transverse axle w, mounted in hearings on the casing a. Attached to or in one with the pinion w is an operating arm or lever 10, controlled by a spring to and having the rocking movement necessary to impart a quarter-revolution to the axle w defined by suitably-arranged stops. On the lever w'is carried a fingerpiece w for manipulating the said lever.

The various parts are so arranged in relation to each other that on operating the lever w the axle '10, carrying the members w, is rotated one quarterof a revolution, and the said members when at rest are always in the position shown; so that the upper casing u is divided into 'two compartments, into one of which the cash is inserted through a slou and falls onto. that member, which for t e time being forms a bottom to said compartment. On 0 crating the lever the cash will then be trans erred to the other com artment by reason of that member formerly ying in a horizontal plane, assuming a vertical osition and forming the central division-wa of the compartments.

In order to lock the members w in their respective positions after movement a doublearmed spring-controlled lever 'w", pivoted to the casing u, carries at its lower end a fork or notched piece w, whichis beveled or so shaped as to allow the members engaging-therewith. when rotating in the direct1on indicated by the arrow, but not to bemoved out of engagement until the lever to is operated to withdraw the said piece '01; out of engagement, which is accomplished by forming on the boss of the lever w a pin w", ada ted to engage. the end of a spring-controlled olt w, carried by the free end of the'lever w The meeting faces both of the pin 'w and the bolt w? are so beveled or shaped as to allow the lever w only being operated on the forward or operative movement of the lever w and not on its return movement, which is effected by the sprin w". Inorder to call attention to the fact 0 thetill being operated a bell is sounded each time the lever w is manipulated by pivoting a double-armed spring-controlled lever'vto the casing -'u, in

. such a position that its one end 12 is in contact with the ratchet-teeth of the wheel wand is adapted to receive movement therefrom. The free end of said lever 'v is formed as a hammer '0 adapted to strike a bell'v The bell and other mechanism are inclosed by a suitable casing '0 The till is operated as follows: The cash received is inserted through the slot u". The lever w is then pulled in the direction of the arrow by means of the finger-piece w, thereby imparting motion to the bevel-wheels and causing the axle to be rotated, owing to the pawl 10. being in engagement with one of the teeth of the ratchet-wheel 'w At the first forward movement of the lever to the notched piece w? is withdrawn from engagement, and

lever w will return by the action of its spring w, the pawl w overriding the teeth of the ratchet wheel, so that no motion will be sliding knob s, each one of which represents a diiferent value c uivalent to'one or more cash uni-ts, a plura ity of contacts equivalent in number with the number of umts re resented on the knob ha .the highest v ue, a sliding contact adag t d to pass over said contacts and make and break circuit on the return movement, means whereby the sliding knobs are caused'to operate the sliding contact soas to cause the number of contacts en-- gaged to corres ond with the number of units represente on the knob operated and a dial in electrical connectionwith the said contacts so arranged as to register each operation of the switchboard, as set forth.
